Energy Levels

Postby jane_ni_2d » Mon Oct 29, 2018 8:11 pm

Why does energy increase when an electron goes up an energy level?

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

Electrons gain energy and become less stable as they move away from the nucleus. As it quantum number increases, the electron gains/absorbs energy from surroundings, which is also known as absorption of energy.
